Vehicle console box

Abstract

To provide a vehicle console box that maintains the function of releasing a seatbelt buckle even after a side collision.SOLUTION: When a side collision occurs, a seat 10 is displaced inward in a vehicle width direction due to a collision load that is input from the vehicle width direction, and a portion closer to a rear portion, of a seat cushion 14 hits a portion closer to a portion behind the vehicle, of a second side wall 22B of a console box 12, causing the second side wall 22B to deform in a direction compressing the console box 12 in the vehicle width direction. As the second side wall 22B deforms, a wedge portion 3804 of an engagement shaft 38 enters a cylindrical portion 4002, to cause the wedge portion 3804 to be engaged with an engagement wall 4004, thereby, preventing the wedge portion 3804 from moving backward.SELECTED DRAWING: Figure 2

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-183908 Summary of the Invention [Problem to be solved by the invention]

[0004] When a side collision occurs and the seat is displaced in the vehicle width direction due to the collision load and hits the side wall of the console box, the side wall is deformed in a direction that compresses the console box in the vehicle width direction. At this time, the seat and the side wall of the console box come close to each other, so the waist of the occupant seated in the seat also comes close to the side wall of the console box, and the buckle becomes sandwiched between the waist and the side wall. When the input of the collision load is released, the seat attempts to return to its pre-crash shape due to the elasticity of the seat frame inside, so the seat is slightly displaced in the vehicle width direction in a direction away from the side wall. At this time, the side wall of the console box also attempts to return to its original shape due to its elasticity in response to the displacement of the seat cushion, so the pinched position formed during the side collision between the occupant's waist and the side wall of the console box is maintained. Therefore, when an occupant unfastens the seat belt, the occupant must apply a large force to the release button, making it difficult for the occupant to easily release the buckle. The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a console box for a vehicle that maintains the seat belt buckle release function even after a side collision. [Means for solving the problem]

[0005] In order to achieve the above-mentioned object, one embodiment of the present invention is a console box for a vehicle in which a console box extending in the fore-and-aft direction of the vehicle is arranged between seats lined up in the vehicle width direction, and a seat belt buckle is arranged between the seat cushion of the seat and the console box, and which is characterized in that when the console box is deformed in the vehicle width direction by the seat cushion during a side collision, a deformation maintaining mechanism is provided inside the console box to maintain the deformed state of the console box. In addition, one embodiment of the present invention is characterized in that the console box has a first side wall and a second side wall that face each other in the vehicle width direction, and the deformation maintenance mechanism is provided between the first side wall and the second side wall, and allows the first side wall and the second side wall to displace in a direction toward each other and prevents the first side wall and the second side wall from displacing in a direction away from each other. In addition, one embodiment of the present invention is characterized in that a pair of reinforcing plates having a vertical height and extending in the fore-and-aft direction of the vehicle are provided on the first side wall and the second side wall, and the deformation maintenance mechanism is provided between the pair of reinforcing plates. In addition, one embodiment of the present invention is characterized in that the deformation maintenance mechanism includes an engagement shaft extending in the vehicle width direction from the first side wall toward the second side wall and having a wedge portion at its tip, and an engagement tube extending in the vehicle width direction from the second side wall toward the first side wall and having a plurality of engagement portions provided therein that allow the wedge portion to enter and prevent the wedge portion from retracting. In addition, one embodiment of the present invention is characterized in that a through hole penetrating in the vertical direction is provided in an upper wall portion that extends in the vehicle width direction and connects the first side wall and the second side wall, at least the upper portions of a pair of wall surfaces that face each other in the vehicle width direction and that constitute the through hole are formed with a hole inclined surface whose distance between them gradually increases as the wall surfaces reach the top, a cup holder having a holder inclined surface that can engage with the hole inclined surface is provided, and the cup holder is arranged in the through hole by aligning the holder inclined surface with the hole inclined surface. [Effects of the Invention]

[0006] According to one embodiment of the present invention, a deformation maintaining mechanism is provided inside the console box to maintain the deformed state of the console box when the console box is deformed in the vehicle width direction by the seat during a side collision. Therefore, by releasing the input of the collision load, space can be secured between the occupant's waist and the console box in the vehicle width direction, and the occupant can insert their fingers into the space secured in the vehicle width direction to operate the buckle release button, maintaining the buckle release operation function. Furthermore, when the console box includes a first side wall and a second side wall that face each other in the vehicle width direction, the deformation maintaining mechanism can be provided between the first side wall and the second side wall. Furthermore, by providing a pair of reinforcing plates on the first and second side walls and locating the engaging shaft and engaging tube between the pair of reinforcing plates, the collision load input from the vehicle width direction during a side collision is absorbed by the pair of reinforcing plates, allowing the console box side walls as a whole to be efficiently deformed in the vehicle width direction. This ensures that a space is secured between the occupant's waist and the console box in the vehicle width direction, allowing the occupant to insert their fingers into the secured space to release the buckle release button. Furthermore, if the deformation maintenance mechanism is configured to include an engagement shaft having a wedge portion and an engagement tube having multiple engagement portions that allow the wedge portion to enter and prevent the wedge portion from retracting, this is advantageous in simplifying the configuration of the deformation maintenance mechanism. Furthermore, a cup holder having a holder inclined surface engageable with a hole inclined surface formed in a through-hole provided in a wall portion extending in the vehicle width direction and connecting the first side wall and the second side wall is provided. When the cup holder is placed in the through-hole with the holder inclined surface aligned with the hole inclined surface, the cup holder moves upward and disengages from the through-hole due to the impact load applied from the vehicle width direction during a side collision. This opens the through-hole and reduces the strength of the wall portion, efficiently deforming the entire side wall of the console box in the vehicle width direction. This ensures a space between the occupant's waist and the console box in the vehicle width direction, allowing the occupant to insert their fingers into the space and operate the buckle release button, maintaining the buckle's release function.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following drawings, the arrow FR indicates the front of the vehicle, the arrow HL indicates the width direction of the vehicle, and the arrow UP indicates the top of the vehicle. As shown in FIG. 8(A), a console box 12 extending in the front-rear direction of the vehicle is disposed between seats 10 arranged in the vehicle width direction. The seat 10 comprises a seat cushion 14 on which the occupant H sits, and a seat back 16 that is supported at the rear of the seat cushion 14 so as to be able to swing via a reclining shaft (not shown) whose axis is oriented in the vehicle width direction at the rear end of the seat cushion 14, and a seat frame (not shown) is provided inside the seat cushion 14 and the seat back 16 to maintain their shape. Shields 18 (covers) made of synthetic resin are attached to both sides of the seat cushion 14 at the rear of the vehicle so as to cover both ends of the reclining shaft. A buckle 20 is disposed between the seat cushion 14 and the console box 12, to which the tongue of a seat belt (not shown) is attached and detached, and the buckle 20 is provided with a release button (not shown) that is operated to disengage the tongue. The buckle 20 is connected to the seat frame of the seat cushion 14 or a floor panel (not shown) via a support stay (not shown) so as to be swingable in the front-rear direction of the vehicle.

[0009] The console box 12 is made of synthetic resin. As shown in Figures 1 and 2, the console box 12 is configured to include a first side wall 22A and a second side wall 22B that extend in the vertical direction and face each other in the vehicle width direction, a front wall 24 that connects the front ends of the first and second side walls 22A and 22B, a rear wall 26 that connects the rear ends of the first and second side walls 22A and 22B, and an upper wall (wall portion) 28 that extends in the vehicle width direction and connects the upper ends of the first and second side walls 22A and 22B, the front wall 24, and the rear wall 26, facing upward. An item storage section 30 that can be opened and closed by a lid is provided at the rear of the console box 12.

[0010] A rectangular through-hole 32 with its long sides extending in the longitudinal direction of the vehicle in plan view is provided in the upper wall 28 in front of the item storage section 30, and a cup holder 34 is provided through this through-hole 32. 2, at least the upper portions of a pair of wall surfaces 3200 that constitute through hole 32 and face each other in the vehicle width direction are formed by a pair of hole inclined surfaces 3202 whose distance gradually increases as the wall surfaces reach the top, and the lower portions of the pair of wall surfaces 3200 are formed by flat surfaces 3204 that face each other with a uniform distance between them. That is, the upper portion of through hole 32 is an upper space S1 formed by the pair of hole inclined surfaces 3202, and the lower portion of the through hole is a lower space S2 formed by the pair of flat surfaces 3204. In one embodiment of the present invention, a pair of hole inclined surfaces 3202 is provided at least on the upper part of a pair of wall surfaces 3200 facing each other in the vehicle width direction, but a pair of hole inclined surfaces 3202 may also be provided over the entire area of ​​the pair of wall surfaces 3200.

[0011] The cup holder 34 includes an upper holder part 34A disposed in the upper space S1 and a lower holder part 34B disposed in the lower space S2. In plan view, holder upper part 34A has a rectangular shape with its long sides extending in the longitudinal direction of the vehicle, and two recesses 3402 for placing cups are provided side by side in the longitudinal direction of the vehicle from holder upper part 34A to holder lower part 34B. The upper holder portion 34A has a pair of holder inclined surfaces 3404 that can engage with the pair of hole inclined surfaces 3202, and the lower holder portion 34B is connected to the lower ends of the pair of holder inclined surfaces 3404 and is formed in a rectangular parallelepiped shape with a uniform thickness in the fore-and-aft direction of the vehicle. The cup holder 34 is arranged in the through-hole 32 by aligning the holder inclined surfaces 3404 with the pair of hole inclined surfaces 3202 and inserting the holder lower part 34B into the lower part of the pair of wall surfaces 3200.

[0012] As shown in Figures 1, 2, and 3, a deformation maintaining mechanism 36 is provided inside the console box 12 to maintain the deformed state of the console box 12 when the console box 12 is deformed in the vehicle width direction by the seat cushion 14 during a side collision. As described above, when a side collision occurs and the seat cushion 14 of the seat 10 is displaced in the vehicle width direction due to the collision load and hits the side walls 22A, 22B of the console box 12, the side walls 22A, 22B are deformed in a direction that compresses the console box 12 in the vehicle width direction, and the deformation maintaining mechanism 36 is a mechanism that maintains the deformed state of the console box 12 in this manner. In other words, the deformation maintenance mechanism 36 is provided between the first side wall 22A and the second side wall 22B that face each other in the vehicle width direction, and is a mechanism that allows the first side wall 22A and the second side wall 22B to displace in a direction that brings them closer together and prevents the first side wall 22A and the second side wall 22B from displacing in a direction that moves them apart. As shown in FIGS. 2, 4 and 5, in this embodiment, the deformation maintaining mechanism 36 is made up of an engaging shaft 38 and an engaging cylinder 40. As shown in FIG. As shown in Figures 4 and 5, the engagement shaft 38 has a shaft portion 3802 extending in the vehicle width direction from the first side wall 22A toward the second side wall 22B, and a wedge portion 3804 which is a one-way engagement mechanism provided at the tip of the shaft portion 3802 that engages in only one direction. The engagement tube 40 includes a tube portion 4002 extending in the vehicle width direction from the second side wall 22B toward the first side wall 22A, and engagement walls 4004 arranged in the axial direction of the tube portion 4002 inside the tube portion 4002 to allow the wedge portions 3804 to enter and prevent the wedge portions 3804 from retracting. Although various conventionally known mechanisms can be used as the deformation maintenance mechanism 36, configuring the deformation maintenance mechanism 36 from an engaging shaft 38 and an engaging tube 40, as in this embodiment, is advantageous in terms of simplifying the configuration and reducing costs.

[0013] Also, as shown in Figures 1, 2, and 3, in this embodiment, a pair of reinforcing plates 42 having a vertical height and extending in the fore-and-aft direction of the vehicle are provided on the first side wall 22A and the second side wall 22B. The reinforcing plate 42 may be provided on the inner surfaces of the first side wall 22A and the second side wall 22B located inside the console box 12, or may be provided on the outer surfaces of the first side wall 22A and the second side wall 22B located outside the console box 12, but in this embodiment, the reinforcing plate 42 is provided on the inner surfaces of the first side wall 22A and the second side wall 22B. The engaging shaft 38 and the engaging cylinder 40 are provided between a pair of reinforcing plates 42 .

[0014] Next, the effects will be described. As shown in Figure 8(A), before a side collision occurs, sufficient space is secured in the vehicle width direction between the waist of occupant H seated in seat 10 and the second side wall 22B of the console box 12, and buckle 20 is positioned in that space.When occupant H unfastens his / her seat belt, occupant H can insert his / her fingers into the space secured in the vehicle width direction to release the release button of buckle 20.

[0015] As shown in Figures 6 and 8(B), when a side collision occurs, the collision load input from the vehicle width direction displaces the seat 10 inward in the vehicle width direction, and a portion near the rear of the seat cushion 14, in this embodiment the shield 18, hits a portion near the rear of the vehicle on the second side wall 22B of the console box 12, causing the second side wall 22B to deform in a direction that compresses the console box 12 in the vehicle width direction. At this time, the seat cushion 14 and the second side wall 22B of the console box 12 come closer to each other, and the waist of the occupant H seated in the seat 10 also comes closer to the second side wall 22B of the console box 12, so that the buckle 20 is sandwiched between the waist and the second side wall 22B. As shown in FIG. 5, as the second side wall 22B is deformed, the wedge portion 3804, which engages only in one direction of the engaging shaft 38, enters the tubular portion 4002 and engages with the engaging wall 4004. After the wedge portion 3804 is engaged, the wedge portion 3804 is prevented from retracting. That is, when the console box 12 is deformed in the vehicle width direction by the seat cushion 14 during a side collision, the deformation maintaining mechanism 36 maintains the deformed state of the console box 12.

[0016] Then, as shown in Figure 8(C), when the input of the collision load is released, the seat cushion 14 attempts to return to its pre-collision shape due to the elasticity of the internal seat frame, and the seat cushion 14 is slightly displaced in the vehicle width direction away from the second side wall 22B. At this time, the second side wall 22B of the console box 12 also attempts to return to its pre-deformation shape due to its elasticity in response to the displacement of the seat cushion 14, but the deformation maintaining mechanism 36 maintains the deformed state of the console box 12, so the second side wall 22B is maintained in the deformed state as shown in Figure 8(C). Therefore, by displacing the seat cushion 14 in a direction away from the second side wall 22B, a space is secured between the lower back of the occupant H and the second side wall 22B of the console box 12 in the vehicle width direction. Therefore, when the occupant H unfastens the seat belt, the occupant H can insert his / her fingers into the space secured in the width direction of the vehicle to release the release button of the buckle 20.

[0017] In addition, in this embodiment, a pair of reinforcing plates 42 are provided on the first side wall 22A and the second side wall 22B, and the engagement shaft 38 and engagement tube 40 are provided between the pair of reinforcing plates 42. As a result, the collision load input from the vehicle width direction due to a side collision is reliably received by the pair of reinforcing plates 42, and the first side wall 22A or the second side wall 22B of the console box 12 is efficiently deformed overall in the vehicle width direction. Therefore, the input of the collision load is released, and the seat cushion 14 is displaced in a direction away from the first side wall 22A or the second side wall 22B, thereby creating space between the occupant H's lower back and the first side wall 22A or the second side wall 22B of the console box 12, so that the occupant H can insert his or her fingers into the created space to release the buckle 20.

[0018] As shown in FIG. 3, when the pair of reinforcing plates 42 are provided so that the movement area within which the shield 18 at the rear end of the seat cushion 14 can move in the fore-and-aft and up-and-down directions of the vehicle is positioned within the contours of the pair of reinforcing plates 42, the first side wall 22A or the second side wall 22B is efficiently deformed in the vehicle width direction as a whole, and space is secured in the vehicle width direction at the portion where the buckle 20 is located. Furthermore, when the pair of reinforcing plates 42 are arranged so that the movement area in which the buckle 20 can move in the fore-and-aft and up-and-down directions of the vehicle is positioned within the contours of the pair of reinforcing plates 42 when viewed from the vehicle width direction, the space between the waist of the occupant H and the first side wall 22A or the second side wall 22B of the console box 12 where the buckle 20 is located is secured.

[0019] In addition, in this embodiment, at least the upper part of a pair of wall surfaces 3200 constituting the through hole 32 in the upper wall 28 connecting the first side wall 22A and the second side wall 22B is formed by a hole inclined surface 3202 whose distance gradually increases as the wall surfaces reach the top, and a cup holder 34 having a holder inclined surface 3404 that can engage with the hole inclined surface 3202 is provided, and the cup holder 34 is arranged in the through hole 32 by aligning the holder inclined surface 3404 with the hole inclined surface 3202. Therefore, as shown in Figure 7, when the first side wall 22A or the second side wall 22B of the console box 12 is deformed in the vehicle width direction due to the collision load input from the vehicle width direction during a side collision, the hole inclined surface 3202 of the through hole 32 in the upper wall 28 connecting the first side wall 22A and the second side wall 22B is deformed in the vehicle width direction, and as a result, the cup holder 34 moves upward via the holder inclined surface 3404 and disengages from the through hole 32. Therefore, by opening the through hole 32 in the upper wall 28 and reducing the strength of the upper wall 28, the first side wall 22A or the second side wall 22B of the console box 12 can be deformed efficiently in the vehicle width direction as a whole. Therefore, the input of the collision load is released and the seat cushion 14 is displaced in a direction away from the first side wall 22A or the second side wall 22B, thereby creating space between the occupant H's lower back and the first side wall 22A or the second side wall 22B of the console box 12, allowing the occupant H to insert his or her fingers into the created space and release the buckle 20.

[0020] Alternatively, the pair of hole inclined surfaces 3202 and the pair of holder inclined surfaces 3404 may be temporarily secured with a small amount of adhesive to prevent rattle of the cup holder 34 while the cup holder 34 is traveling, allowing the cup holder 34 to detach from the through hole 32 in various types of side collisions.
